"We are pleased to be releasing a set of improvements to Windows 8 in broad areas of performance, power management and battery efficiency, media playback, and compatibility. These improvements are available starting today via Windows Update. We wanted to briefly talk about our improvements to the engineering system and in particular the speed at which we were able to deliver these updates to you." Good stuff. They're also updating the core Metro applications to make them less useless.

Don't they use the IP address to get something resembling a location (at least the area of a country you're in)?

They seem to use wifi router BSSID or ESSID since these can be scanned by streetview etc cars rather easily. Naturally Google has a different database for that than Microsoft.

After moving, Google continued to mis-locate me for a couple of years at my old place - with geoIP they'd at least figured out that this must be wrong (public-facing IPs by German ISPs are rather easily to resolve to city level thanks to data in DNS, and I moved a couple 100 kilometers, ending up in an entirely different net block), but that didn't seem to bother them.
